Are all these news items re. toddlers killing family members for real?

“In many of these shooting cases, a toddler finds a gun and accidentally shoots himself with it, 27 out of the 43 toddler shootings involved self-inflicted injuries. Earlier this month in Ohio, for instance, a 3-year-old boy found his father’s loaded gun in the kitchen and fatally shot himself in the head with it.”

“But shootings of other people are common, as well. Last weekend in St. Louis, a 2-year-old found a loaded handgun and accidentally shot and killed his father, who was asleep at the time.”
How is it physically possible for a 2 or 3 yr. old to 1)lift the gun up (in some cases I guess) and then 2)be strong enough to pull the trigger, and hit a person at the crucial enough place to severly injure and/or kill?
